STERILIZING OUTFIT.

Specification of Letters Patent.

Patented July is, 1921.

Application filed October 30, 1917. Serial No. 199,269.

To all whom it may concern.

Be it known that l, WVILLIAMT. Pownn, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in sterilizing Outfits, of which the following is a specification.

My invention relates in general to a pocket sterilizing outfit and specifically relates to a hypodermic syringe case for containing all the requisites necessary to the administration of hypodermics.

One of the objects of my invention is to provide a simple, inexpensive type of outfit, of the above indicated character, designed to have the least possible dimensions for containing a complete sterilizer, independent of the container, and co-acting instruments all arranged to utilize practically all of the available space within the container.

Another object is to provide a construction permitting the ready demounting of the parts so that the separated units may be moved independent of each other and each designed to constitutea holder or stand to provide a firmsupportand opened to permit ready access, to the devices carried thereby. Further and incidental desideratuins are to provide a construction for facilitating the manipulation of the instruments under sterile conditions, for insuring the mounting of the instruments in fixed position and for protecting the instruments against accidental injury while carried in the pocket.

Various other objects and advantagesof the invention will be in part obvious from an inspection of the accompanying drawings and-in part will be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set claims, parts will be identified by specific names for convenience of expression but they are intended to be as generic in their application to similar parts as the art'will permit. 7

In the drawings there is shown an open end container 4, in this disclosure shown to be a hollow metal tube, elliptical in crosssection so as to provide a rounded case designed to lit the pocket. One end of the container is closed by means of a cap 5 having a flat endwall 6 constituting a broad support-base for the container and for the cap when the same is demounted from the contamer. v

A peripheral flange 7 outlines the wall. 6 and telescopes either end of the container with a frictionally tight'fit to retain the cap in place. A complete sterilizing outfit 8 is welded or otherwise fixed centrally-to the wall 6 on the flanged side thereof. The sterilizer includes an open top concaved bowl 9 having a configuration in plan substantially that of the interior cross-section of the container so that the transverse dimensions of the container will be dependent upon the necessary capacity of the bowl. The

bowl is preferably designed to contain just sufficientwater, so that when boiled, there will be enough sterile water .to charge the syringe carried by the. outfit and to keep the needles submerged during the sterilizing procem. j

The bowl is spaced in fixed position from the cap by means of a burner 10. This burner may be of any conventional form and is illustrated to include a fuel chamber 11 adapted to contain blocks of solid alcohol positioned the requisite distance below the bowl to obtain the maximum heating effect from the small cakesof alcohol used with the instrument. These cakes are of a size just sufficient to bring the measured quantity of water in the bowl to a boil and the lOO fuel chamber is proportioned to contain this measured amount of fuel.

A bridge piece or cradle 12 for supporting the instruments below the water level is constructed to extend across the bowl parallel to the major axis thereof. The piece is a metal strip reduced in width intermediate its ends to form broad supporting parts 13 arranged to rest on the upper edge of the bowl with the intermediate part 14 depressed to approach the bottom of the bowl. The reduced depressed portion is provided with a pair of open top U spring clips 15 arranged to hold the instruments parallel to each other and'at a slight angle to the'length of the strip. One end of the strip is bent down to form a holding end 16 by means of which the bridge piece may be grasped in removing the hot instruments from the bowl. 7

A cap 17 similar to the cap 5 is arranged to close the opposite endof the container.

Astud 18 provided with an inwardly 'facing threaded socket 19 is positioned centrally on the flanged side of this cap and is designed to have the usual threaded cap end of a hypodermic syringe v20 insertedtherein. V The syringe extends axially-of the con tainer and the parts are so proportioned that wlththe caps in place the syringe will extend as far as possible into the concaved bowl thus economizing in the length of the container.

j The syringe illustrated is of the class in whichthe needle tips 21 may be removed from the barrel and thus further insuring a minimum length to the container. In the device illustratedtwo such needle tips are shown threaded to studs 22 position'edon opposite sides of the syringe proper: i

A plurality of vials orinstrument' cases 23 generally used in connection with a de- 7 'vice'of this'characterare fixed to the inside of the container preferably by welding the same in place. Placing these 1 articles close to the-wall alarge number maybe disposed between the'wall and themembers carried. bythe caps.

This invention contemplates the' assembling of-the parts as illustrated without permanently connecting the several parts in.

fixed position and in the case of the sterilizer the bowl may be pivotally mounted to the frame and designed to be swung out of the way and thus permit the ready insertion of the fuel;

In operation andassuming that the outfit is in the assembled "position shown in Fig. 1,; the operator removes the/bottom cover 5 and sets thesame upright in position onany suitable-support. This provides a completeopen-toprbowl sterilizer which permits ready access to the fuelchamber and 7 provides a construction 1n which a' small portion of-water may be readily introduced into the" bowl. The operator then ,withdraws the cover 17 from the container and inverting the same lays the cover on its the bowl. The h1 1 charge is then ignited and the water in the bowl brought to a boil.

this sterilizes the needles as is common with operations of this character. By grasping the handle 16 the needlesinay be withdrawn from thewater in position to have the end of the syringe screwed into position thereon.

The sterile water may then be utilized to charge the syringe or to dissolve any medicaments to be used. V 1

These medicaments may be contained within one of the vials 23 and'it is obvious that other needles and other instruments maybe contained in these vials or may take the place'of thesame.

The container with one or both caps removed may be arranged to rest on one end thus presenting the articles 13 in spaced apart position to'be conveniently withdrawn as needed by the operator. When the operation is completed, the contents of the vials may be returned'to the same, the syringe parts demount'efd and screwed to their carrying cap and both caps slipped on to the ends of the container thus packing the outfit in its carrying position. r

By means of a deviceof this character all of the necessary appurtenances for giving a "hypoderm c vor other similar. treatment,

may be contained in asimpleform of reconvenientlyfit the pocket of-the operator. Practically all of the available space within the container is utilized. vVhile retaining all of the advantages of an open bowl type of sterilizer the otherwise j wasted space jtalzenup by the depth of the bowl is utilized to contain part of the. longest instrument to V "ceptacle of minimum capacity designed to be'carried bytheoutfitn, The parts-are ar-- ranged in either telescoped' orin offset relation so that the space" is utilizedand'each part 'has its allotted space without any necessity'of dividing partitions or'oth'er parts which might-increase-the weight-of the de-.

. :The parts'ofthe sterilizer are 'accurately proportioned so. as-to obtain the greatest V heating eflects "withithe' limited amount of fuel carried and the bowl is-so arranged that other receptacles may be positionedyon the bowl to provide a douhleheater should *it he desired to" heata substance by 'means of a boiling liquid. The "instrument @parts fixed to the cover 17 are held rigid in position 7 and separated from any possiblez contact with othermembers, thus assuring'prm tection to the needle "points and permitting ready 7 access to the same when 'the' support "mg'coverz 'sremoved.

Whil'e .1 'have' showni'an'dsdescribedand have pointed out in theaanne'xed claims, certain novel features ioffimylinvention will be understood-that"various omissions; 1 sub. "stitutions :and changes in the form and :de-

v tails of the device illustrated. and in :its Top- 'eration may be made by those skilled in the art without departing from the spirit of the invention.
